Answer:

(a) Region of higher potential

(b) ΔV=1.911V

Explanation:

For Part (a)

Proton moves into a region of higher potential because it must goes in opposite direction of force to get rest

For Part (b)

Potential difference we can calculate bu definition of kinetic energy

ΔK=mv²/2= -qΔV

express in ΔV

ΔV= -mv²/2q

Substitute the given values

So

ΔV= -mv²/2q

=-\frac{mv^2}{2e}\\ =\frac{9.11*10^{-31}*(8.20*10^{5}m/s)^2}{2*1.602*10^{-19}}\\ =1.911V

ΔV=1.911V

A particle accelerator fires a proton into a region with a magnetic field that points in the x-direction. (a) If the proton is m
iVinArrow [24]

Answer:

<em>The magnitude of the magnetic field will act in a direction towards me.</em>

<em></em>

Explanation:

When a charged particle enters a magnetic field, it is deflected. The direction of travel of the particle is deflected, but the kinetic energy of the particle is not affected. <em>The force experienced by a charged particle as it enters a magnetic field that acts perpendicular to the path of the velocity of the particle, will produce a force that is perpendicular to both the direction of travel of the particle and the direction of the magnetic field.</em> In this case, the proton moves in the y-direction, the magnetic field is in the x-direction, therefore the force experienced by the particle will be towards me.
